Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
